| 17:00 | Avoid 32-bit overflow when calculating the byte offset of an overflow page in SQLITE_DIRECT_OVERFLOW_READ code. Fix for [ac0ff496b7]. (check-in: c5256b59 user: dan tags: trunk) | |

| Title: | Database corruption due to integer overflow with SQLITE_DIRECT_OVERFLOW_READ | |||
| Status: | Fixed | Type: | Code_Defect | |

| Description: | ||||
|
When the (non-standard) compile-time option SQLITE_DIRECT_OVERFLOW_READ
is used, a 32-bit integer overflow at /artifact/80ea65224512?ln=3982
will likely cause the database to be reported as corrupt. The database
is not really harmed by this, but attempts to read the database will be
unsuccessful.
This bug has existed since the SQLITE_DIRECT_OVERFLOW_READ option was added on 2011-10-08 by check-in [2ab14a8467278571]. | ||||
